Enquiry preparation
Oven: describe the installation you have
For a oven enquiry: Explain whether the appliance has a furniture front, is stacked, is built into a cabinet or stands free. Leave connected equipment and surrounding furniture in place.
We agree suitable work and arrangements for your actual appliance.

For the appliance you actually own
Record the cavity, temperature setting and mode that was in use. A lit display or running fan can coexist with a heating problem on a particular function.
How this supports the discussion
The oven reference, fitting and observation allow a more specific discussion. They do not establish a failed part or guarantee a repair.
Confirm the proposed attendance
Confirm suitable work, proposed charges and access with the team. An enquiry notebook is preparation, not a reserved visit.
